4; Claims; 1.

This invention relates to a pail pump and particularly to a detachablepail pump adapted to piercean initially sealed container or pail filledwith lubricating oil; grease or some-other fluid.

It is an object of the invention to provide a pump for a container offluid which is provided with a piercing device and a pump handle.

It is'anotherobject of the invention to provide a pail pump havingapump.handlewhich is movable to a position wherein itmay be used as a carryinghandle;

With these and other objects in view, my invention consistsintheconstruction, arrangement and combination of the various parts of mydevice whereby the objects contemplated are attained; as hereinaftermore fully'set forth, pointed. out in my claims and illustrated in the.accompanying drawings, wherein:

Fig; I is a view partially insection oi. my pail pump inserted in acontainer filled .with ,fluld', the dotted lines showing'th'e handle inthe. carrying position; and

Fig; 2 is an enlargedpartial sectionallview'of the piston and checkvalve of the pump.

Referring specifically to. the: drawing for a detailed. description ofthe. invention numeral I-I designates. a sealed container or pail for afiuid I2 such as lubricating oil. The container I2 is, for example, afive gallonlubricant container.

A pump, generally indicated at I3, comprises a body portion l4 having ascrew clamp I5 at its side to clamp the pump on the container I2 after ahollow sharp piercing member l6 has pierced the top of the container I2and had its opening positioned near the bottom of the pail, so that allthe liquid may be pumped out.

The body portion I4 is provided with a passage II communicating at itslower end with the hollow piercing member I6 and at its upper end with ahorizontal passage I8 which forms a cylinder for a piston I9. The pistonI9 i pivotally connected at 2| to a link 22 which is in turn pivotallyconnected at 23 to a handlemember 24. The bodyportion I4 also has aspring pressed check valve 25 positioned at the outlet end of thecylinder I 8. The valve 25 comprises a stationary plate 26 having anopening 21 therein and a movable valve plate 28 which is pressed againstthe stationary plate 26 by a spring 29. The entire valve assembly isheld in position by a threaded plug 3| so that the valve may be easilyremoved and repaired or replaced if necessary. The plug 3| is providedwith an internally threaded opening 32 to which is attached a flexibleoutlet hose 33. If desired, a suitable lubricating fitting 34 may beprovided on the end of the hose.

A container" of this type containing lubricating 2 oil' orgrease must becarried; from place-to place around an automobile that is beinglubricated. The handle 24' is pivoted at 35 and is movable to theposition shown in dotted lines in Fig. 1' so that the container and pumpmaybe easily-carried around. Thehandl'e 24, when in the carryingposition, engages shoulder 36 on pump body I4 and orients the angularposition of the container II in a predetermined position, preferably"upright or' substantially vertical; The piston I9 and cylinder I8 are ofsufiicient length thatthepiston does not slip out of the cylinder whenthe handle is in the carrying position. Itwillalso' benoted that whenthe container H is being carried by handle 24, the handle does notimpose-on piston I9- any force which is in a direction transverse to'the axis or the piston. This is because the handle 24 is pivoted tothepump body I4 and is pin connected to the-piston I9 by means oflink-'22 and pins 2| and 2-3;

When-the handle 24 is in the pumping positionas-shown in Fig. 1, and isreciprocated, lubricant orgrease is-drawn' up through thehollow piercingmember I 6 into the passagel'l and cylinder l 8 and is forced outthrough the valve 28 into the passage 32-and hose 33 on the dischargestroke of the piston.

From the foregoing it will be apparent that I have provided an improvedpump for an initially sealed container of lubricant, grease or otherliquid, which is particularly adaptable for carrying from place to placeby means of the pump handle which is readily movable to a convenientpump carrying position.

Some changes may be made in the construction and arrangement of theparts of my device without departing from the real spirit and purpose ofmy invention, and it is my intention to cover by my claims any modifiedforms of structure or use of mechanical equivalents which may bereasonably included within their scone.

I claim as my invention:

1. A hand pump for a portable initially sealed container of fluidcomprising a body portion, a hollow sharp piercing member attached tothe body portion and adapted to pierce the top of the container, aclamping means for retaining the pump in position on the container, apiston, a cylinder for the piston and a discharge valve all in said bodyportion, an outlet conduit connected to said body portion, a handle forthe pump connected to said piston, means including a pivotal connectionaffording movement of said handle to a substantially vertical carryingposition, wherein movement thereof does not efiect pumping, or

to a substantially horizontal pumping position, wherein reciprocatingmovement thereof effects pumping of the fluid from the container, and ashoulder on said body portion adapted to engage the handle when saidhandle is in the substantially vertical carrying position, whereby whenthe container is carried by means of the pump handle, said pump handleengages said shoulder and orients said container in a predeterminedposition without imposing any forces on said piston in a directiontransverse to the axis of said piston.

2. A hand pump for a portable initially sealed container of fluidcomprising a body portion, a hollow sharp piercing member attached tothe body portion and adapted to pierce the top of the container, aclamping means for retaining the pump eccentrically in position on thecontainer, a. piston, a cylinder for the piston and a discharge valveall in said body portion, an outlet conduit connected to said bodyportion, a handle for said pump, means for connecting the handle to saidpiston comprising a link pivotally attached to the handle and saidpiston, said handle also being pivotally attached to said body portion,said pivotal connection affording movement of said handle to asubstantially vertical carrying position or to a substantiallyhorizontal pumping position, and a shoulder on said body portion adaptedto engage the handle when said handle is in the substantially verticalcarrying position, whereby, when the container is carried by means ofthe pump handle, said pump handle engages said shoulder and orients saidcontainer in a predetermined position.

3. A hand pump for a portable container of fluid comprising a pump body,means for eccen trically securing said pump body to said portablecontainer, a pump within said pump body, a pump handle, means connectingsaid pump handle to said pump, pivotal means for connecting the pumphandle to the pump body, said pivotal means afiording movement of saidpump handle to a carrying position, and said pump body having a shoulderportion adapted to engage the pump handle when said handle is in thecarrying position, whereby, when the container is carried by means ofthe pump handle, said pump handle engages said shoulder and maintainssaid container angularly oriented in a predetermined position withoutimposing any forces on said pump in a direction transverse to thedirection in which the forces during pumping are ordinarily applied tosaid pump.

4. A hand pump for a portable container of fluid comprising a pump body,means for eccentrically securing said pump body to said portablecontainer, a pump piston within said pump body, a pump handle, a pivotedlinkage connecting said pump handle to said piston, pivotal means forconnecting the pump handle to the pump body, whereby reciprocal pivotalmovement of the pump handle through a range of positions actuates thepiston through said linkage, said pivotal means affording movement ofsaid pump handle to a substantially vertical carrying position, and saidpump body having a shoulder portion adapted to engage the pump handlewhen said handle is in the carrying position, whereby, when'thecontainer is carried by means of the pump handle, said pump handleengages said shoulder and maintains said container in a substantiallyupright position.
